Description
Comparison between Hot Oil Column Forming Method and Oil Ammonia Column Spheroidization Method
Hot oil column forming and oil ammonia column forming are both methods of forming in oil, that is, the sol material can be converted into gel under certain conditions, the process is operated in the oil environment, and gel beads with certain fixed shape are prepared according to the tension of the oil, and then the target product is obtained through drying, aging, roasting and other processes. The basic principle of oil ammonia column forming balls is the same as that of hot oil column forming. Both methods can be used to produce alumina carriers in fixed bed and moving bed industrial production.
